Chronic pancreatitis （CP） is a chronic disease characterized by recurrent inflammation and progressive damage to pancreatic tissue， and its deterioration may increase the risk of pancreatic cancer in patients with CP， which seriously threatens the health of patients with CP. In recent years， studies on the pathogenesis of CP have mostly focused on the activation of pancreatic stellate cells （PSCs） and its role in pancreatic fibrosis. This article elaborates on the mechanism of action of PSCs in CP， summarizes the current status of research on effective traditional Chinese medicine components and prescriptions for intervention of PSCs in the treatment of chronic CP， and proposes the future research directions for effective traditional Chinese medicine components and prescriptions， so as to provide a reference for the clinical treatment of CP patients in the future.

OBJECTIVE To explore the mechanism of improvement effect of Chanbao zhichuang suppository （CBZCS） on hemorrhoids in rats through network pharmacology and metabolomics. METHODS A hemorrhoid model was established by subcutaneous injection of rhododendron oil to induce anal swelling. SD rats were divided into blank group （NC group， 0.32 g/kg vaseline）， model group （Model group， 0.32 g/kg vaseline）， CBZCS low-， medium-， and high-dose groups （CBZCS-L， CBZCS- M， CBZCS-H groups， with dosages of 0.16， 0.32， and 0.64 g/kg respectively）， and Mayinglong musk hemorrhoids suppository group （Positive group， 0.32 g/kg）， with 9 rats in each group. Anal administration was performed at 6， 12， 24， 48， and 72 hours after modeling. After the last administration， the pathological changes of the anal tissues in rats were observed， and the serum levels of interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） in rats were detected. Differential metabolite analysis and enrichment analysis were conducted by metabolomics methods， and the target proteins of CBZCS in treating hemorrhoids were obtained by network pharmacology. The core metabolic pathways were screened by interaction and enrichment analysis of differential metabolites and proteins， and the core proteins were experimentally verified. RESULTS Compared with the NC group， the anal tissues of the Model group showed obvious lesions， and the levels of IL-6 and TNF- α in the serum were significantly increased （P＜0.05）； compared with the Model group， the pathological damage of the anal tissues in the treatment groups was alleviated to varying degrees， and serum levels of IL-6 in CBZCS-H group， CBZCS-M group， and Positive group as well as serum levels of TNF-α in CBZCS-H group were significantly reduced （P＜0.05）. The metabolomics results showed that 34 differential metabolites were screened from the anal tissues of rats， and 22 of them showed a return after CBZCS administration. The differential metabolites mainly enriched in arachidonic acid metabolism， histidine metabolism， and glycerophospholipid metabolism. Through the network pharmacology， 138 intersection genes of CBZCS against hemorrhoids were determined. The analysis results showed that differential metabolites and target proteins were mainly enriched in the arachidonic acid metabolism pathway， and the regulation of this pathway might be related to cyclooxygenase-2 （COX-2）， Myc proto-oncogene protein （c-MYC）， cytochrome P450 1B1 （CYP1B1）， interleukin-1β （IL-1β）， and IL-6 protein expression. The experimental verification results showed that the expression levels of key proteins （COX-2， c-MYC， CYP1B1， IL-6， IL-1β） in the anal tissues of the Model group were significantly higher than those in the NC group （P＜0.05）， and the levels of the above proteins in the anal tissues of CBZCS-H group and Positive group were significantly lower than those in the Model group （P＜0.05）. CONCLUSIONS The mechanism of CBZCS in treating hemorrhoids may be to inhibit the expression of COX-2， c-MYC and CYP1B1 proteins， thereby inhibiting arachidonic acid metabolism and reducing the release of inflammatory factors IL-6 and IL-1β.

Objective To investigate the role of lncRNA SNHG1 in homocysteine-induced pyroptosis of podocyte.Methods Cbs+/-mice were randomly divided into two groups:a normal diet group(ND)and a high me-thionine diet group(HMD).Western blotting was used to detect the protein expression levels of Caspase-1,Cleaved Caspase-1,and NLRP3.Mouse renal glomerular podocytes were cultured in vitro,and then assigned into a control group(Control,0 μmol/L Hcy)and a homocysteine intervention group(Hcy,80 μmol/L Hcy).Western blotting was used to detect the protein expression levels of Caspase-1,Cleaved Caspase-1,and NLRP3.Mouse renal glomerular podocyion group(OE-NC + Hcy)and the lncSNHG1 overexpression + homocysteine intervention group(OE-SNHG1 + Hcy)were also established.After 48 hours of intervention,Real-time fluorescence quantita-tive PCR was used to detect the expression of lncSNHG1 in podocytes after Hcy intervention.Western blot was used to detect the expressions of Caspase-1,Cleaved Caspase-3 and NLRP3.Immunofluorescence was used to de-tect the expression levels of GSDMD and GSDMD-N.ELISA was used to detect the contents of IL-1β and IL-18.Results(1)In the animal experiments,the expression levels of pyroptosis-related proteins Caspase-1,Cleaved Caspase-1,NLRP3,GSDMD,and GSDMD-N were all increased in the HMD group compared with the ND group.(2)In the cellular experiments,the expression levels of Caspase-1,Cleaved Caspase-1,NLRP3,GSDMD,and GSDMD-N were all increased in the Hcy group compared with the Control group,and the contents of pyroptosis-mediated inflammatory factors IL-1β and IL-18 were increased as well.(3)In the cellular experiments,the expres-sion of lncSNHG1 was increased in the Hcy group compared with the control group.After transduction with lnc-SNHG1 lentivirus,the expression of lncSNHG1 was increased in the OE-SNHG1 group,compared with the control group and the OE-NC group.(4)In the cellular experiments,the expressions of pyroptosis-related proteins Cas-pase-1,Cleaved Caspase-1,NLRP3,GSDMD,and GSDMD-N were increased compared with the OE-NC+Hcy group,and the contents of pyroptosis-mediated inflammatory factors IL-1β and IL-18 were increased in the OE-SNHG1+Hcy group.Conclusion These results indicate that lncSNHG1 may play a role in promoting Hcy induced podocytepyroptosis.

BACKGROUND:The assessment of asymmetric gait quality plays a pivotal role in guiding rehabilitation training;however,the link between gait quality and kinematic-kinetic gait parameters remains ambiguous. OBJECTIVE:To formulate a machine-learning model for evaluating gait quality based on gait parameters,identify factors sensitive to gait quality from asymmetric gait parameters,investigate the relationship between gait indicators and gait quality,and provide guidance for asymmetric gait training and rehabilitation. METHODS:An asymmetric gait database was established through the creation of asymmetric conditions.Kinematic and kinetic data were collected from 8 young and 8 elderly subjects(all male,right dominant population)during gait tests.Gait quality for each test data set was assessed using symmetry indices,resulting in the creation of a gait parameter-gait quality dataset.Utilizing the Random Forest algorithm,a gait quality evaluation model was developed and key quality parameter factors were identified through differential analysis.This model was iteratively refined.The model's performance was evaluated through 10-fold cross-validation,and its effectiveness was verified using the cross-validation dataset. RESULTS AND CONCLUSION:(1)A gradient test was designed to categorize gait quality into optimal,suboptimal,intermediate,and poor groups,with 759,329,133,and 125 instances,respectively.(2)The application of the Random Forest algorithm in gait quality assessment was explored.A relationship model was established between gait indicators and gait quality,yielding a predictive model accuracy of 95.99%.(3)The 13 main parameters significantly influencing asymmetric gait quality were identified through the Random Forest model's feature importance ranking.(4)An analysis of gait quality sensitivity factors using the 13 important parameters led to the identification of five key sensitivity indexes.The Random Forest model utilizing these sensitivity factors achieved a predictive accuracy of 94.20%.

Objective: To examine the developmental trajectory of fine motor ability in schoolage children with attention deficit hyperactivity disorder (ADHD) for two years, so as to provide scientific evidence to promote motor development in ADHD children. Methods: From April to June 2019, 31 children aged 6-8 years old were selected from a public elementary school. They were diagnosed with ADHD by two psychiatric professionals according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. Additionally, 31 typical developmental children, matched for age, sex and IQ with the ADHD group, were recruited as the control group. Fine motor ability was assessed with tasks of hand manual dexterity in Movement Assessment Battery for Children-2 (MACB-2), and a followup assessment was conducted from April to June 2021. The development changes of fine motor ability between two groups of children were compared by using t test and repeated measures analysis of variance. Results: Between baseline and followup periods after two years, the total score of hand fine motor in the ADHD group did not show significant improvement (7.4±3.0, 8.0±3.4; t=-1.05, P>0.05), while there was a small effect size improvement in typically developing control group (9.5±2.1, 10.5±2.4; t=-2.12, effect size=0.38, P<0.05). Followup after two years, coin/peg throwing scores with dominant hand improved between ADHD group and control group (7.0±3.3, 9.5±3.2; 8.4±2.8, 11.6±1.6) (t=-3.74, -6.33, P<0.01; effect size=0.67, 1.14), with a smaller improvement in the ADHD group. The score for threading beads/threads decreased in between ADHD group and control group (7.9±2.4, 5.8±3.1; 9.2±1.1, 8.2±1.9) (t=3.89, 2.78, P<0.01; effect size=0.70, 0.50), with a greater decrease in the ADHD group. Conclusions The development speed of fine motor ability in children with ADHD aged 6-8 is slow and continues to lag behind normal developmental children. Fine motor development in children with ADHD should be closely monitored, and targeted interventions should be implemented when necessary.

Objective To examine the effect of ground cage use on Oncomelania hupensis spread, so as to provide insights into precision snail control. Methods Twenty ground cages that were frequently used to capture rice field eels were purchased, including 11 packaging tape-made cages, 7 plastic cages and 2 nylon rope-made cages. The eel-capturing activity was mimicked, and 20 ground cages were assigned in settings with relatively high (1.00 snail/0.1 m² and higher) and low snail densities (< 1.00 snail/0.1 m²) in Xindai Township, Pinghu City, Zhejiang Province during the period from 15 : 00 to 8 : 00 of the following day on April 13, 26 and 28. The numbers of snails carried by different types of ground cages were compared in settings with different types of snail densities using the rank-sum test. Results A total of 11 cage-times were assigned in settings with a high snail density, and a total of 77 snails were captured, with a mean number of 7 snails in each cage-time and 2.15 snails in 0.1 m² ground cage. The mean numbers of snails carried by packaging tape-made and plastic cages were 2.47 snails/0.1 m² cage and 0.37 snails/0.1 m² cage, respectively. A total of 24 cage-times were assigned in settings with a low snail density, and a total of 8 snails were captured, with a mean number of 0.33 snails in each cage-time and 0.09 snails in 0.1 m² ground cage. The mean numbers of snails carried by packaging tape-made cages were 0.12 snails/0.1 m² cage; however, no snails were carried by plastic or nylon rope-made cages. The number of snails carried by ground cages was higher in settings with a high snail density than in settings with a low snail density (Z = −4.019, P < 0.01), and the number of snails carried by packaging tape-made cages was higher in settings with a high snail density than in settings with a low snail density (Z = −4.086, P < 0.01). No significant differences were found in the numbers of snails carried by different types of ground cages. Conclusion The use of ground cage in snail habitats is a contributor to snail spread.

Objective: To investigate the prevalence of osteoporosis (OP) and its influencing factors among people aged 60 years and above, so as to provide insights into OP prevention and treatment among the elderly. Methods: People aged 60 years and above who underwent physical examinations were selected from Hangzhou First People's Hospital from January to October 2023. Demographic information, lifestyle and physical examination data were collected through field surveys and hospital information systems. Bone density was measured by dual-energy X-ray densitometer, and OP was diagnosed with reference to the Guidelines for the Diagnosis and Treatment of Primary Osteoporosis (2022). Factors affecting the OP were identified using a multivariable logistic regression model. Results: A total of 482 participants were included and had a mean age of (69.10±6.52) years. There were 217 men (45.02%) and 265 women (54.98%). The prevalence of OP was 43.36%. Multivariable logistic regression analysis identified gender (women, OR=3.791, 95%CI: 1.726-8.314), age (70 to 79 years, OR=1.260, 95%CI: 1.018-1.559; 80 years and above, OR=3.083, 95%CI: 1.546-6.147), body mass index (≥24 kg/m2, OR=0.358, 95%CI: 0.205-0.626), family history of fracture (OR=1.475, 95%CI: 1.073-2.030), diabetes (OR=1.626, 95%CI: 1.109-2.382), regular exercise (OR=0.457, 95%CI: 0.287-0.726), intake of milk products (OR=0.511, 95%CI: 0.335-0.780), intake of calcium supplements (OR=0.473, 95%CI: 0.287-0.778) and vitamin D deficiency (OR=2.132, 95%CI: 1.309-3.473) as factors affecting OP. Conclusion The prevalence of OP is associated with gender, age, body mass index, family history of fracture, diabetes, diet and vitamin D deficiency.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective: To evaluate the risk of fine particulate matter (PM2.5) on excess mortality among residents. Methods: The data of residential mortality in Yangzhou City, Jiangsu Province from 2015 to 2021 were collected from the Chinese Disease Prevention and Control Information System. The average daily mass concentration of PM2.5 and meteorology data were collected from the Yangzhou Environmental Monitoring Station and Yangzhou Meteorological Bureau, respectively. The effects of PM2.5 on non-accidental mortality, morality of respiratory diseases and mortality of circulatory diseases were evaluated using a generalized additive model. The risk of excess mortality was evaluated using excess risk (ER) and the number of excess mortality. Results: The median average annual mass concentration of PM2.5 was 38.00 (interquartile range, 31.95) µg/m3 in Yangzhou City from 2015 to 2021, decreasing from 51.75 (interquartile range, 32.82) µg/m3 in 2015 to 28.00 (interquartile range, 23.42) µg/m3 in 2021. The median average annual number of non-accidental mortality, mortality of respiratory diseases and mortality of circulatory diseases were 96 (interquartile range, 22), 9 (interquartile range, 5) and 38 (interquartile range, 13) cases, respectively. The greatest effects of per 10 μg/m3 increase in PM2.5 mass concentration on non-accidental mortality, mortality of respiratory diseases, and mortality of circulatory diseases were seen at a cumulative lag of 1 day (ER=0.528%, 95%CI: 0.293%-0.763%), a cumulative lag of 2 days (ER=0.917%, 95%CI: 0.125%-1.714%) and a cumulative lag of 1 day (ER=0.595%, 95%CI: 0.232%-0.961%), respectively. The number of excess mortality caused by PM2.5 on non-accidental mortality, mortality of respiratory diseases, and mortality of circulatory diseases in Yangzhou City from 2015 to 2021 were 2 125, 412 and 977 cases, respectively; compared with 2015, the number of excess mortality in 2021 decreased by 66.95%, 75.53% and 64.42%, respectively. Conclusions An increase in the mass concentration of atmospheric PM2.5 may elevate the risk of excess mortality among residents. Compared to 2015, the number of excess deaths attributed to exposure to atmospheric PM2.5 declined in 2021.
